1. Researchers in Penn State University’s Department of Geography created an augmented reality app to give users more background about one of the oldest and best-known monuments on the school’s University Park campus. The Obelisk was constructed in 1896 from regional rocks and minerals, and its 281 stones are arranged in order by geologic time period. “There’s a database connected to each stone, so whenever you touch any stone in the app, you can see where it came from, how old it is, and other information,” says Arif Masrur, doctoral student in geography. “Eventually our goal is to also include 360-degree photos of the actual environment from where each rock was excavated.”
